The first heavy snow fall of the year covered parts of Dublin this morning, with some areas of the capital, and many areas around the country waking up to a blanket of snow.
Met Eireann have issued a status orange low temperature weather warning for the whole country from 8 o'clock this evening.
Freezing temperatures between minus 2 and minus 8 degrees are expected tonight.
Slippery paths and treacherous roads also due to snow accumulation and ice.
Ruth Jephson from AA Roadwatch has advised motorists to leave plenty of distance between cars if you're on the road today.
"A lot of people will need to leave time to defrost the windscreen of their cars. If you are making any journeys and come across ice or snow on your route remember that gentle maneuvers are key."
"It can take you up to 10 times longer to stop your car in this type of conditions so make sure you stay well back from the vehicle in front of you."
Gardaí also say that any snow must be cleared from the roof of the car, as it can fall onto the windscreen while braking, potentially causing restricted vision.
